Steven Powell Convicted of Voyeurism

The father-in-law of missing mom Susan Powell was convicted Wednesday of voyeurism in Tacoma, Wash. Police uncovered surreptitious images of Susan and of disrobing girls who lived next door while investigating Susan's December 2009 disappearance.

Steven Craig Powell, 62, was convicted of 14 counts of voyeurism after a weeklong trial that included testimony from the two girls, who were 8 and 9 when the incidents occurred in 2006, and are now 13 and 15.

He faces up to 70 years in prison.

Prosecutor Grant Blinn said in his closing arguments Tuesday that the girls were unaware that Powell was quietly photographing them through an open window. "They had no idea at the time that this defendant was lurking in the shadows of his own bedroom," Blinn said.
